Hi All,
I hope this is the right place. Please feel free to point me towards others that might have faced similar issues.
Setup:
Windows 10
dump1090 v1.10.3010.14
monitoring traffic with PlanePlotter
Variation A:
FA 1090Mhz aerial + 5m cable
FA filter
FA Pro Stick
Variation B:
dvb-t RTL dongle
standard dvb-t aerial
I was at Luton today to get some ADS-B data. As I am not really interested in long range, but more interested in runway and ground coverage, I thought it would be great to place my kit near the tower.
Interestingly when I used Variation A, I had great long distance coverage, all the way to the north of France. Flights dropped out at about 500ft above ground and I had rarely any AC on ground.
When I used Variation B, however, I lost most of my long distance range and picked up more AC on ground.
Do you have any idea why this would happen?
Is it a hardware issue with the dongle/aerial/ filter?
Is it a setting in dump1090/planeplotter?
My initial idea was that dump1090 might have been overwhelmed by the amount of flights it had picked up and then prefereably only reports the flights further away. Another thought was that the signal of AC so close might be too strong for the aerial, so the cheaper areal, due to its loss actually performs better in that environment.
However, when I did something similar at Bristol I did not face those issues and had sufficient ground coverage.
Hope someone has an idea and can help.
Thank you.
